Pull networking fixes from Jakub Kicinski: "Including fixes from netfilter and can. Current release - new code bugs: - tcp: add a missing sk_defer_free_flush() in tcp_splice_read() - tcp: add a stub for sk_defer_free_flush(), fix CONFIG_INET=n - nf_tables: set last expression in register tracking area - nft_connlimit: fix memleak if nf_ct_netns_get() fails - mptcp: fix removing ids bitmap setting - bonding: use rcu_dereference_rtnl when getting active slave - fix three cases of sleep in atomic context in drivers: lan966x, gve - handful of build fixes for esoteric drivers after netdev->dev_addr was made const Previous releases - regressions: - revert "ipv6: Honor all IPv6 PIO Valid Lifetime values", it broke Linux compatibility with USGv6 tests - procfs: show net device bound packet types - ipv4: fix ip option filtering for locally generated fragments - phy: broadcom: hook up soft_reset for BCM54616S Previous releases - always broken: - ipv4: raw: lock the socket in raw_bind() - ipv4: decrease the use of shared IPID generator to decrease the chance of attackers guessing the values - procfs: fix cross-netns information leakage in /proc/net/ptype - ethtool: fix link extended state for big endian - bridge: vlan: fix single net device option dumping - ping: fix the sk_bound_dev_if match in ping_lookup" * tag 'net-5.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (86 commits) net: bridge: vlan: fix memory leak in __allowed_ingress net: socket: rename SKB_DROP_REASON_SOCKET_FILTER ipv4: remove sparse error in ip_neigh_gw4() ipv4: avoid using shared IP generator for connected sockets ipv4: tcp: send zero IPID in SYNACK messages ipv4: raw: lock the socket in raw_bind() MAINTAINERS: add missing IPv4/IPv6 header paths MAINTAINERS: add more files to eth PHY net: stmmac: dwmac-sun8i: use return val of readl_poll_timeout() net: bridge: vlan: fix single net device option dumping net: stmmac: skip only stmmac_ptp_register when resume from suspend net: stmmac: configure PTP clock source prior to PTP initialization Revert "ipv6: Honor all IPv6 PIO Valid Lifetime values" connector/cn_proc: Use task_is_in_init_pid_ns() pid: Introduce helper task_is_in_init_pid_ns() gve: Fix GFP flags when allocing pages net: lan966x: Fix sleep in atomic context when updating MAC table net: lan966x: Fix sleep in atomic context when injecting frames ethernet: seeq/ether3: don't write directly to netdev->dev_addr ethernet: 8390/etherh: don't write directly to netdev->dev_addr ...
